ribosome rescue protein RqcH, archaeal type; This HMM (built with support from arCOG01695) describes archaeal homologs of the RqcH (Ribosome-associated Quality Control H), involved in release of defective mRNAs that lack a stop codons and so are stuck on ribosomes. Conservation of a role in ribosome rescue for this archaeal family is supported by presence in a conserved gene neighborhood with homologs of Pelota/Dom34 and ABCE1/Rli1 homologs, proteins involved in splitting the ribosome into large and small subunits.
The actual alignment was detected with superfamily member NF041120:

NFACT protein RNA binding domain; This domain occurs in proteins that have been annotated as Fibronectin/fibrinogen binding protein by similarity. This annotation comes from Swiss:O34693 where the N-terminal region is involved in this activity. It is an RNA binding domain of the NFACT (NEMF, FbpA, Caliban, and Tae2) proteins. This NFACT-R family is found in two eukaryotic gene contexts: fused to the NFACT-N and NFACT-C domains in the NFACT protein involved in the ribosomal quality control pathway which contributes to CAT-tailing and as a standalone domain. Additionally this domain contains a conserved motif D/E-X-W/Y-X-H that may be functionally important.

NFACT N-terminal and middle domains; This family contains the N-terminal and middle domains of NFACT (NEMF, FbpA, Caliban, and Tae2) proteins from eukaryotes, archaea and bacteria. Many members of this family act in ribosome quality control (RQC), including RqcH, which are involved in the addition of a poly-Ala tail to defective translated proteins to tag them for degradation. This process is analogous to the ssrA/tmRNA bacterial system. However, some other NFACT family members, such as bacterial proteins FbpA in Listeria or PavA in Streptococcus, are exported (despite lack of a classical signal peptide) and behave as fibronectin-binding adhesins associated with virulence.

Click on the triangle to view details about the feature, including a multiple sequence alignment
of your query sequence and the protein sequences used to curate the domain model,
where hash marks (#) above the aligned sequences show the location of the conserved feature residues.

This image shows a graphical summary of conserved domains identified on the query sequence.
The Show Concise/Full Display button at the top of the page can be used to select the desired level of detail: only top scoring hits
(labeled illustration) or all hits
(labeled illustration).
Domains are color coded according to superfamilies
to which they have been assigned. Hits with scores that pass a domain-specific threshold
(specific hits) are drawn in bright colors.
Others (non-specific hits) and
superfamily placeholders are drawn in pastel colors.
if a domain or superfamily has been annotated with functional sites (conserved features),
they are mapped to the query sequence and indicated through sets of triangles
with the same color and shade of the domain or superfamily that provides the annotation. Mouse over the colored bars or triangles to see descriptions of the domains and features.
click on the bars or triangles to view your query sequence embedded in a multiple sequence alignment of the proteins used to develop the corresponding domain model.
The table lists conserved domains identified on the query sequence. Click on the plus sign (+) on the left to display full descriptions, alignments, and scores.
Click on the domain model's accession number to view the multiple sequence alignment of the proteins used to develop the corresponding domain model.

Concise Display shows only the best scoring domain model, in each hit category listed below except non-specific hits, for each region on the query sequence.

(labeled illustration) Full Display shows all domain models, in each hit category below, that meet or exceed the RPS-BLAST threshold for statistical significance.
(labeled illustration) Four types of hits can be shown, as available,
for each region on the query sequence:
specific hits meet or exceed a domain-specific e-value threshold
(illustrated example)
and represent a very high confidence that the query sequence belongs to the same protein family as the sequences use to create the domain model
non-specific hits
meet or exceed the RPS-BLAST threshold for statistical significance (default E-value cutoff of 0.01, or an E-value selected by user via the
advanced search options)
the domain superfamily to which the specific and non-specific hits belong
